H A D | dp_aux.c | 9fc41843 Wed Jan 13 13:00:00 CST 2021 Kuogee Hsieh <khsieh@codeaurora.org> drm/msm/dp: unplug interrupt missed after irq_hpd handler
There is HPD unplug interrupts missed at scenario of an irq_hpd followed by unplug interrupts with around 10 ms in between. Since both AUX_SW_RESET and DP_SW_RESET clear pending HPD interrupts, irq_hpd handler should not issues either aux or sw reset to avoid following unplug interrupt be cleared accidentally. This patch also postpone handling of irq_hpd until connected state if it happened at connection pending state.
Changes in V2: -- add postpone handling of irq_hpd until connected state -- check DP_TRAINING_1 instead of DP_TRAINING_NONE
